The photo blitz lasted an hour or two on Monday afternoon, during which Bing's 91,000 Twitter followers were bombarded with links to photos taken at a Saturday Night Los Angeles Confidential magazine party that was sponsored by Bing.

"At the LA Confidential party presented by @Bing," Microsoft said in Twitter message after Twitter message.

Microsoft didn't seem to know exactly what happened, but a spokeswoman said Monday that the account was not hacked. "It was not our intention to flood the Twitter feed, we have remedied the situation and apologize for the inconvenience," she said via e-mail.
